SAND-BOX,

SPECIFICATION forming part of Letters Patent No. 610,590, dated September 13, 1898.

' Application filed March 8, 1898- Serial No. 673,120. (No model.)

To all whom it may concern:

Be it known that I, THOMAS J. STANTON, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented certain new and use ful Improvements in Sand-Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

This invention has reference to a novel construction in sand-boxes and mechanism for delivering the sand to rails or other points where it is needed, and is adapted, more especially, for use in connection with locomotives, the object being to provide devices by means of which the sand can be effectively delivered and which prevents the clogging of the sand within the sand-pipe or sand-box by reason of moisture, waste, or other foreign matter.

The invention consists in features of construction hereinafter fully described and specifically claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation, partially in vertical section, of a sand box and accompanying devices constructedin accordance with this invention; Fig. 2 is a top plan of the bottom of the sand box. Fig. 3 is a bottom plan of the same. Fig. at is a vertical section, taken on an enlarged scale, of the lower end of the sand-box and the sand-pipe. Fig. 5 is a detail section showing the chain brush lowered. Fig. 6 is a detail perspective of a section of the chain brush.

Referring now to said drawings, 1 indicates the sand-box, which may be of any approved construction and which is provided at oppo site sides with openings 2, from which lead the sand-pipes 3. These sand-pipes extend down wardly on both sides of the locomotive and are provided at their lower ends with nozzles 4, that are situated to deliver the sand to the rail and in front of the wheel. The upper end portion of the nozzles t is straight, as shown at 5, while thelower end portion is curved to the rail, and the-joint between the nozzles and the lower end of the sand-pipe 3 is preferably screw-threaded, as shown, provided, however, with a removable set-screw vided with a plurality of teeth 9, that extend in the direction in which the valves move to open the box, so as to carry to one side waste, clogged sand, or other matter that may prevent the further entrance of the sand into the openings 8, as is obvious. The inner end of the valve is rigidly secured to a rotatable pin 10, that passes through the sand-box and projects below'the lower end thereof. Secured to these pins 10, below the bottom of the box, are arms 11, that extend to one side and are connected on their outer ends by a bar 12, that is pivoted to both of the arms, whereby the valves are caused to move in unison. The arm 11 at one side of the sand-box is provided with a laterally-extending portion 13, that is pivotallyconnected with the forward end of the operating-rod 14:, that extends rearwardly into the cab of the locomotive, as shown. The rear end of this rod 14 is provided with a toothed portion 15, whereby the rod can be held in retracted position by a pawl 16, so as to regulate the extent to which the valve is open and also for the purpose of holding it in its position. v Y Y Situated within the sand-pipe and nozzle is a chain brush 17 and a scraper-18. The chain brush is connected with the valve and extends downwardly and into the nozzle, while the scraper 18 is connected with the lower end of the chain brush and is curved toconform with the curvature of the lower end of the nozzle. The said chain brush and scraper are adapted to be raised when the valve is open, so as to loosen the sand within the sand-pipe and nozzle and to effectuallyprevent clogging. The connection between the chain brush and the valve comprises a link 19, the upper end of which is pivoted within one end of the recess 20 in the lower side of the valve, while its lower end is pivoted to the upper endof the chain brush. Said link19 fits within the said recess 20, and the parts are so arranged that when the valve is open the link is raised and passes into the recess, whereby the chain brush is raised to an extent equal tothe length of the link. The said chain brush is composed of a plurality of links 21 and 22. Each of these links is provided with a winged head 23, having rearwardly-extending lugs 2-1011 their outer ends, the said winged headbeing at right angles to the body portion of the link adjoining links 22.

the upper link of the chain brush and the link 19 comprises a fiat link 29, having a'slot and in opposite directions to the wings on the The connection between 30 at one end to receive the head 23 of the upper link of the chain brush, while the otherend of the link 29 is provided with eye-lugs 31, between which the lower end of the link 19 is pivoted.

It is seen from the foregoing description that the chain brush consists of a plurality of winged links wherein the wings on alternate links extend in opposite directions, so that when the chain is moved within the sandpipe it effectually cuts and breaks the mass of sand and prevents clogging.

Thelower end of the chain brush when the valve is closed extends to the upper end of the curved portion of the nozzle, and the scraper 18, which consists of a shank 32, havinglaterally-extending wings 33, and which istapered toward its lower end, is connected with the lower end of the chain brush by means of a loop 34, that passes through the slot in the lower link of the chain brush and between the ends of which the upper end of the scraper is secured. Fastened upon the saidloop 34 is a ring 35, that fits within the straight portion of the nozzle. A spring 36 is situated within the straight portion of the nozzle and bears at its opposite ends against the ring 35 and the lower end of the sandpipe, which is situated within the upper end of the nozzle.

Near the upper end of the nozzle is a port 37, from which leads an inclined pipe 38, that communicates with a source for supplying steam or compressed air, wherebya downward blast can be generated within the nozzle to not only prevent the sand from clogging between the convolutions of the spring 36, but also serves to create a pressure-vacuum above the port 37 to feed the sand into the nozzle and also gives blast to force it through the nozzle.

In operation it is seen that when the operating-rod 14 is moved to open the valve the links 19 elevate the chain brush and scraper for the purpose above described and permit the sand to pass intothe sand-pipe, while the blast from the pipe 38 forces the sand through the nozzle When the operatingerod is released and the valves close, the weight of the chain brush and scraper, together with the force of the springs 36, draws the chain brush and scraper to their normal position and to the lower limit of their movement.

Having thus described the invention, what is claimed as new is- 1. The combination with a sand-box provided with openings in the bottom thereof, sand-pipes leading. from said openings, and nozzles at the lower end of said sand-pipe, of valves controlling said openings in the bottom of the sand-box, anoperating-rod for said valves, movable chain bru shes and scrap ers situated withinsaid sand pipes and nozzles and connected at their upper ends with the valves so as to beraised whenthe valves are open, and to be lowered when the valves are closed,.and means for creating a blast in said nozzles.

. 2. The combination with a sand-box having an opening in the bottom thereof and a sand-pipe leading from said opening, oi: a valve pivoted to slide upon the bottom of said sand-box and tocontrolsaid opening, means for sliding said valve, a recess in the lower side of said valve, a link having one end pivoted within said recess, and a chain brush situated within the sand-pipe and connected with the other end of said link.

3. The combination with a sand-box having a depending sand-pipe provided at. its lower end with a nozzle, of a valve for controlling the upper end of the sand-pipe, a chain brush connected with said valve and extending into the sand-pipe and provided at its lower end with a scraper situated within the lower end of the nozzle, a spring for depressing said chain brush and scraper, and a blastpipe communicating with said nozzle.

4. The combination with a sand-box having a sand-pipe and a nozzle at the lower end of the sand-pipe, a valve for controlling the upper end of said sand-pipe, a chain brush connected with said Valve and extending into said sand-pipe, a scraper at the lower end of the chain brush extending to the lower end of the nozzle, a ring secured to the lower end of said chain brush, a spring situated within the nozzle and hearing at its opposite ends against said ring and the lower end of the sand-pipe, and a blast-pipe communicating with the lower end of the sand-pipe.

5. A chain brush for the purpose set forth comprisinga plurality of links yieldingly connected together and provided with laterallyextending wings, the wings on one link extending at right angles to the body of the link and in the opposite direction from the wings of the adjoining links.
